My invention relates to provements in educational toy blocks forteaching children to select and put together articles of differentsizes, shapes,

and colors, in like or different sizes and color combinations and,incidentally, testing their aptitude as regards perception of size,color and shape.

Other and subordinate objects, within the purview of my invention,together. with the precise nature of my improvements will be readilyunderstood when the succeeding description and claims are read withreference to the drawing accompanying and forming part of thisspecification.

In said drawing: V

Figure 1 is a view in perspective illustrating my invention in apreferred embodiment thereof;

Figure 2 is a view in vertical longitudinal section;

Figure 3 is a view in perspective of a modification of the invention;and

Figure 4 is a similar view of another modification of the invention.

Referring to the drawing by numerals, according to my invention asillustrated in Figures 1 and 2, an elongated rectangular, flat, baseblock I is provided with a plurality of top, threaded cylindricalsockets 2 in the longitudinal center thereof spaced apart equidistantly,preferably, and of the same diameter, preferably although notnecessarily.

A set of cylindrical blocks 3 of the same size are provided for stackingn the base block I with the blocks attached together in the stack and tosaid base block. For this purpose, the blocks 3 are provided with axialthreaded bores 4 preferably of the same size, in diameter, as one of thesockets 2. Screw plugs 5 are provided, one for turning into one socket 2to extend out of the same so that one block 3 may be threaded thereon,and the others for turning into the bores 4 of subjacent blocks 3 in thestack to project above such V blocks for the attachment of the blockstogether in stacked concentric formation.

Another set of rectangular successively smaller blocks 6, I, 8 areprovided for stacking on the base'block I. This set of blocks isdesigned to be stacked with smaller blocks on top of larger blocks withthe stack attached to the base block I and the blocks of the stackattached together by the following means. Stepped bores 9 are providedin the center of these blocks 6, 1 with larger Screw 'A pplication Mytw, 19ras iama2aj612 :"1o1aim. (01535-73) eter, are provided, one forturning into one of the sockets 2 to project out of the same for turningof the larger end of the bore In of the larger block 6 onto the same tosecure said block to the base block land the others for turning into thesmaller ends of the bores 9 to project out of the same for turning ofthe larger ends of successively smaller blocks 1, 8 thereon to securethe blocks of the set together.

In the modification of the invention illustrated in Figure 3, acruciform shaped block is provided with a central bottom screw plug l3fast thereto for turning into one of the sockets 2, and also with a topcentral threaded socket M for turning into the same a screw plug onanother similar block so that such blocks may also be secured togetherin stacked formation with the stack attached to the base block I.

In the modification of the invention shown in Figure i, a rectangularblock I5 is provided with a bottom screw plug l6 and a top threadedsocket l'i like the screw plug l3 and socket [4 of the cruciform blockl8 of Figure 3 and for the same purpose, and said block I5 is providedwith threaded side sockets l9 for attachment of other similar blocks tothe sides thereof by the screw plugs 16 thereof.

All of the set of blocks may be colored differently, respectively, forarrangement in stacked formation in corresponding colors in the stack,but, it has not been deemed necessary to illustrate the blocks ascolored. 7

As will now be seen, the blocks of my invention and the means forattaching the same together and to the base block I are especiallydesigned to teach attaching articles together in like or dif- Theforegoing will, it is believed, suflice to,

impart a clear understanding of my invention, without furtherexplanation. I

Manifestly, the invention, as described, is susceptible of modification,without departing from the inventive concept, and right is hereinreserved to such modifications as fall within the scope of the appendedclaim.

Having described the invention, what is claimed as new is:

A set of educational and intelligence testing blocks for childrencomprising an elongated base block, sets of blocks for stacking on saidbase block, the blocks in one set being alike, and the blocks in theother set being difierently shaped than the biocksiof the isetfirst-r'nentioned and of successively smallersize in-the set, likedevices of the same size and character for securing each block of thefirst-mentioned set to a lower block in the stack and the lowermostblockvof-"the stack to said base block, and devices fofsbufing eachblock of the second-mentioned set -to -a lower block of the stack andthe lowermostblo ck oi the stack to the base block comprisii'iglilie"devices-- of different sizes relatively, whereby toteach'cl'iildren the difierence between like and unlike articles and thedifference between articles of different sizes.
